EGG BOILER.

' Application filed November 24, 1928. Serial No. 876,817. I

To all whom it may concern:

Be it known that I, ANGELO CESARE PA- nonr, a citizen of the United States of Amerce, and a resident of Jersey City Heights, 1n the county of Hudson and State of New Jersey, have invented a new and Improved Egg Boiler, of which the following is a description.

My invention relates to a known form of egg boiler in which the eg basket is adapted to be automatically lifte from the boiler after a lapse of a predetermined number of minutes for which the device is set.

In the known form of egg boiler to which my invention particularly relates certain defects lessen the practicability of the egg boiler and the general object of my invention is to overcome the defects referred to. One of the known defects is the mounting of the chain ulley. In the usual way of making the evice a comparatively li ht casin is required to withstand the strains to w ich the pulley is subjected by rough usa e as for example due to a sudden pull of t e chain, thereby causing the Wei ht to strike the pulley or arts adjacent t ereto at the top of the egg oiler, the result being that the casin becomes distorted and the chain frequently displaced from the pulley.

My present invention overcomes the defeet referred to and makes it impossible for rough usage to disrupt the assemblage and it serves to insure a proper guiding of the chain at all times.

A 'further defect in the known form of egg boiler in question heretofore made is due to the fact that steam rising from the boiler and contacting with the box containing the clock work assemblage causes expansion of the box and permits steam to enter with the result that the mechanism in the box becomes rusted. I provide an im roved form of box the expansion of which will not permit steam to enter to the interior of the box.

A ain, in the eg boiler referred to as usua ly made, a bri ge piece is secured to the frame or casing in which bridge piece the gage pinion is located. The bridge iece and the coacting parts in the assemlage as usuall made involve a lar e number of parts he d together with smal screws and the arrangement does not ermit the pinion gage to be well lubricate nor does the construction enable the parts to resist rough handling. I overcome the defects referred to by an improved bridge piece.

Again, in the egg boiler in question as usually made the means to lubricate the shaft of the ratchet pinion leaves much to be desired and my invention includes a means to overcome the defects by providing a construction greatly simplified and more effective in permitting the lubrication of the shaft of the ratchet pinion.

Reference is to be had to the accompanying drawings forming a part of this specification, it being understood that the drawings are merely-illustrative of one example of the invention.

Figure 1 is a pers ective view of an egg boiler generally of nown form in which my improvements are embodied;

Figure 2 is a perspective view on an enlarged scale of the u per end of the egg boiler showing the pu ley mount separated from the casing;

Figure 3 is a front view of the clock work box with the cover removed;

Figure 4 is a detail through the bridge piece and a portion of the clock train as indicated by the line 44, -Figure 3;

Figure 5 is a perspectiveview of the bridge piece for the gage pinion;

Figure 6 is a horizontal section line 6-6, Figure 3;

Figure 7 is a horizontal section on the line 77 Figure 1; g

Figure 8 is an enlarged section line 88, Figure 6.

The numeral 10 indicates a tubular stand ard or casing; 11, the clockwork box; 12, the egg basket having a rod 13 adapted to be lifted by an upward movement of the chain 14 which in practice is actuated by the drop in -of ,a weight (not shown) in the standin 10. The dropping of the weight is controlled by clockwork mech-. anism accordingto the position of the set ting slide 15 in a well known manner. The parts referred to are well known .as features of the egg boiler to which the invention pertains and need no further description on the on the here.

In the operation of the egg boiler the steam rising from the vessel into which basket 12 is lowered heats the clockthe e box 11 and in the expansion of the work nos

box under the heat of the steam, the bottom" of the box and the front 18 thereof separate leaving an inlet for the steam at the joint between the bottom and cover. To overcome the objection referred to I form bottom 16 with a front lip 17 extending beneath and flush with the cover 18 so that there is no direct o enin for the steam to pass into the box. The 11p 17 referred to is best shownin Figure 7.

The defective pulley or sheave assemblage in the egg boiler to which the invention pertains is remedied in my improvements as followszlnstead of the pulley pin being passed through the sides'of the casing or standard 10 leavin said sides to withstand the strains I provide cheeks between which the pulley 19 is snugly accommodated with just suflicient clearance to revolve. Said cheeks 20 are depending from the top plate 21 of the ulley mount and possesses rigidity to effectively withstand any strains exerted on the pulley. The pulley pin 22 projects beyond the cheeks 20 at each side so as tq abut against the inner-surface of the sides of the casing or standard 10, the pin being thus held against longitudinal isplacement without straining said casing. The cheeks '20 are formed with thickened portions or lateral bosses 120 and a transverse pin hole 23 is produced through the bosses 120- and cheeks 2O beneath the top plate 21 so that a pin can be assed through the hole 20 and through t e registering holes 24 through the sides of the casing 10 as part of the means for securing the pulley mount in said casing. In front of the casing 10 a vertical opening 25 is formed into n which the cheeks 20 extend to project beyond the front of the casing, there being a complementary slot 26 extendin from the bottom of the opening 25 to aifor clearance for the pulley 19. At the back of'the top plate 21 is a depending flange 27 which is formed with screw holes, there being registering' holes 28 in the back of the case 10 so as to receive fastenin screws for securing the flange 27 to said ack of the casing.

The numeral. 28 indicates the usual lug on the pulley mount formed with a tooth 29 to engage the teeth 31 on the setting bar 15. The numeral indicates a slot-in the pulley mount in which the setting bar 15 has guided movement.

The numeral 32 indicates the bridge piece fastened by screws 33 to the back of the clockwork box 11, the screws taking into tapped holes 34 in said bridge piece. The bri ge piece supports the shaft 35 of the gage pinion 36 and in the usual construction the assemblage invplving the bridge 32 and'pinion 36 includes a number of small arts held together by screws, the parts hemg liable to disarrangement and looseness. I form a slot 37 for that pinion of the clocklifting means for said egg work engagin the gage pinion 36 and I provide a was er 38 on the inion shaft 35, said washer being accommo ated in a recess 39 in the bridge 32. After the washer 38 is placed in the recess 39 the opposite edge ortions 40 of the wall of said recess are ndented or upset to retain the washer 38 m position.

In Figure 6 the numeral 41 indicates an extension block suitably secured as by a screw or screws 42 to the back of the clockwork box 11, said extension forming a hearing for the shaft 43 of the ratchet pinion 44 of the clockwork. A lubricating means for the shaft 43 is defective in the usual construction of the egg boiler to which the invention relates and the construction shown in Figures ,6 and 8 provides an effective lubrication. The bushing 45 fitted on the shaft 43 extends partially into a recess 46 leaving an annular channel 47 for the lubricant to which channel an oil hole 48 leads downwardly. An opening 49 is formed in a wall of the standard or casing 10 through which a nozzle of an oil can may be inserted supplying oil to the oil hole 48.

I would state in conclusion that while the illustrated example constitutes a practical embodiment of my invention, I do not limit myself strictly to the exact details herein illustrated, since, manifestly, the same can be considerably varied without departure from the spirit of the invention as defined in the appended claims. 7

Having thus described my invention, I claim:
